2. Magnetometer - Wikipedia

   en.wikipedia.org/wiki/Magnetometer

   A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field.

3. Electromagnetic shielding - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_shielding

   Electromagnetic shielding. Electromagnetic shielding cages inside a disassembled mobile phone. In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating ...

4. Eddy current - Wikipedia

   en.wikipedia.org/wiki/Eddy_current

   v. t. e. In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops within conductors, in planes ...

5. Magnetic monopole - Wikipedia

   en.wikipedia.org/wiki/Magnetic_monopole

   In particle physics, a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). [1] [2] A magnetic monopole would have a net north or south "magnetic charge". Modern interest in the concept stems from particle theories, notably the grand ...

6. Induction loop - Wikipedia

   en.wikipedia.org/wiki/Induction_loop

   Induction loop. An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or ...

7. Metal detector - Wikipedia

   en.wikipedia.org/wiki/Metal_detector

   A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft, and a variable-shaped pickup coil. When the coil nears metal, the control box signals its presence with a ...

8. Magnetic levitation - Wikipedia

   en.wikipedia.org/wiki/Magnetic_levitation

   Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation ( maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.
